Pear resistance to psilla (Cacopsylla pyri L.): A review	2013	16	.pdf	application/pdf	13486	633	56	Effectiveness of yellow sticky- board traps have been examined by several authors and seasonality of the catch and flight activity of pear psylla (C. pyricola) according to weather conditions have been reported (Krysan and Horton, 1991; Horton, 1994; Civo- lani and Pasqualini, 2003; Erler, 2004), as well as diur- nal difference (Horton, 1993) and intraorchard changes in distribution associated with leaf fall (Horton et al., 1993).
